られている。PRIOR TECHNOLOGY AND PROBLEMS The operation of brazing electrical connections to a conductive strip on an electrically heated glass window is difficult when an additional enamel layer, such as an opaque enamel, is applied to the conductive strip and the glass surface. It is known that there is. To circumvent this difficulty, in European Patent Application No. 0 070 771, openings (windows) are provided in the opaque layer provided below the electrically conductive strip at a location below the electrical connection member, so that the electrically conductive When printing the sexual layer, use printing paste (
It is known to pass the conductive material (which is later fired into a conductive strip) through the apertures at those locations so that the conductive material is fused directly to the glass surface at those locations.

を受理する能力がその正規のレベルのまま保持される。When a ceramic paste is printed on the enamel layer and then baked to create a conductive layer on top of the vitreous enamel layer, the resulting conductive layer cannot be brazed due to the presence of the glass phase in the conductive layer. It is known that it is difficult to Upon baking, a low-melting glassy phase forms in the enamel and flows into the conductive outer layer, thereby changing the composition of the conductive layer and causing the free metal particles in the conductive layer to be completely or partially covered by the glassy phase. It is believed that it will be destroyed. This glass phase prevents the brazing material from coming into contact with the metal particles and thus inhibits subsequent brazing.If the surface of the conductive layer that is to receive the brazing material is treated according to the invention, the conductive layer will accept the brazing material. The ability to do so remains at its normal level.
